Security Engineer plays a key role in securing our cloud infrastructure and application development as well as related security tooling. You will work closely with our Infrastructure and Development teams, and support them in security related questions. In practice, this means (at least) the following:

  • Developing, implementing and maintaining cloud security architecture, policies and procedures

  • Collaborating with game and infrastructure teams to identify, evaluate and mitigate security risks and integrate security into our development lifecycle

  • Continuously improving the security of cloud infrastructure via means of automation


Every role is eventually shaped to match our unique passions, backgrounds and strengths. Here are some of the key skills and experience you should already have when joining Metacore as a Security Engineer:

  • Extensive, all-round experience in Cloud Security, Application Security, or DevSecOps roles

  • Background in securing production workloads in Amazon Web Services (AWS)

  • Knowledge of security automation and infrastructure automation tools (Terraform, CloudFormation)

  • Deep understanding of cloud security best practices and risk-based approach in securing environments

  • Ability to support infrastructure and game teams with infrastructure, development as well as application build and deployment process related security questions

In addition to these, it would be nice but not mandatory for you to have these as well:

  • Familiarity with mobile application development, application and API security, and CI/CD pipelines (Github Actions)

  • Experience of conducting threat modeling in cloud native environment and application development

  • Practical know-how of Kubernetes (EKS) or other serverless and container technologies

  • Hands-on knowledge in security incident investigation and response in cloud environments

Sounds about right? Then let’s talk!
